Hi.

Welcome to Ubuntu and the Forums.

Finding your way around Ubuntu and the documentation for it can be a bit tricky. This thread will hopefully help point you towards reliable sources of information, and also tell you how to get the most out of these forums when a search doesn't reveal the answer.

System
Recovery - Type the phrase “REISUB” while
holding down Alt and SysRq (PrintScrn) with
about 1 second between each letter. Your system
will reboot.
lsb_release -a - get Ubuntu version
uname -r - get kernel version
uname -a - get all kernel information
